Abstract
A replaceable development station usable for developing electrostatic images in an apparatus having a toner monitor and a channel for slidably receiving the development station includes a chamber containing a supply of a development mixture of toner and carrier particles. A recess is defined in one wall of the chamber for receiving the toner monitor, the recess being defined by a thinned region of the wall such that the toner monitor is separated from the developer mixture by a wall region substantially thinner than the general wall thickness.
